Requirements

• 3+ years of commercial software development experience with Java
• Advanced proficiency in Spring Framework / Spring Boot, including deep understanding of its internals and ecosystem
• Solid hands‑on experience with Angular and modern front‑end application development
• Proven background working with large‑scale enterprise applications and complex legacy codebases
• Strong knowledge of REST APIs, backend architecture, and distributed systems principles
• Deep understanding of common application security vulnerabilities (OWASP Top 10), secure coding practices, and threat mitigation techniques
• Demonstrated ability to independently investigate security findings, identify root causes, and design appropriate, sustainable fixes
• Advanced skills in dependency/library upgrades, migration planning, and resolving complex compatibility issues
• Excellent troubleshooting, problem‑solving, and analytical skills
• Ability to work autonomously, take ownership of complex initiatives, and collaborate effectively within a distributed team
• Experience mentoring other engineers and contributing to technical direction
